Between capitalist and communist society there lies the period of the revolutionary transformation of the one into the other. Corresponding to this is also a political transition period in which the state can be nothing but the revolutionary dictatorship of the proletariat.

In its struggle for power the proletariat has no other weapon but organisation. Disunited by the rule of anarchic competition in the bourgeois world, ground down by forced labour for capital, constantly thrust back to the 'lower depths' of utter destitution, savagery, and degeneration, the proletariat can, and inevitably will become an invincible force only through its ideological unification on the principles of Marxism being reinforced by the material unity of organisation, which welds millions of toilers into an army of the working class.

Strikes, boycott, parliamentarism, meetings and demonstrations are all good forms of struggle as means for preparing and organising the proletariat. But not one of these means is capable of abolishing existing inequality. All these means must be concentrated in one principal and decisive means; the proletariat must rise and launch a determined attack upon the bourgeoisie in order to destroy capitalism to its foundations. This principal and decisive means is the socialist revolution.

Society is undergoing a silent revolution, which must be submitted to, and which takes no more notice of the human existences it breaks down than an earthquake regards the houses it subverts. The classes and the races, too weak to master the new conditions of life, must give way.

All freed, fast-frozen relations, with their train of ancient and venerable prejudices and opinions, are swept away, all new-formed ones become antiquated before they can ossify. All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.

In view of the undoubted honesty of those broad sections of the mass believers in revolutionary defencism who accept the war only as a necessity, and not as a means of conquest, in view of the fact that they are being deceived by the bourgeoisie, it is necessary with particular thoroughness, persistence and patience to explain their error to them, and to prove that without overthrowing capital it is impossible to end the war by a truly democratic peace.
